Continuation of application Serial No. 360,632, June 10,

Claims. 01. 132-36 The instant application is a continuation of our copending application Serial No. 360,632, filed June 10, 1953, and relates to a hair setting device and method of setting hair dry which constitute an improvement over the invention covered by our prior application.

The primary object of the present invention is to provide a hair setting device and method whereby heat is applied to a dry molded tress of hair while uniform tension is exerted on the entire molded tress and while the molded tress'is restrained against distortion.

Another object of the invention is to provide a hair setting device in the form of a clamp having a heat generating means on one of its arms and a means associated with one of the arms to enter the center of the molded tress for the purpose of maintaining the tress in its proper molded position during the setting thereof.

A further object of the invention is to provide a hair setting device in the form of a clamp having a heat generating means on one of'itsarms, the initial relative positions of the'arms being such that when they are opened to receive a molded tress, they extend substantially parallel to each other so that uniform tension is applied to the entire molded tress.

Another object of the invention is to provide a hair setting device of the character described which, in addition to being functional, is simple, inexpensive, attractive and easy to manipulate.

And yet another object of the invention is to provide a method of setting hair dry in which the molded tresses can be safely, completely and effectively set in so short a time that one can begin successively to remove the heat-producing clamps immediately after the last clamp,

had been applied to a tress.

These and other objects of the invention will become more apparent as the following description proceeds in conjunction with the accompanying drawing, wherein:

Figure 1 is a side elevational view of the hair setting device;

Fig. 2 is a top plan view thereof;

Figure 3 is a bottom plan view thereof and illustrating the manner in which a pin curl is retained therein;

Figure 4 is a perspective view of a chemical packet employed in the device;

Figure 5 is an enlarged longitudinal sectional view through the device; and

Fig. 6 is a diagrammatic perspective view of the device and illustrating the manner of applying an additional chemical therein.

Specific reference will now be made to the drawings wherein similar reference characters are used for corresponding elements thoughout.

The present device, indicated at 10, is essentially a clamp with a heat-generating means associated therewith and including additional means, as will appear hereinafter, to retain a tress of molded hair in a firm and proper position during the setting thereof. The device comprises an upper arm 12 and a lower arm 14 which are provided adjacent their rear ends with cooperating ears 16 and 18 carrying a pivot pin 20., A suitable spring 22 embraces the pivot pin and bears against the inner is a container 28 to the top of which is hinged as at 30 a lid 32 for access to the interior of the container. The

lid is provided with a plurality of vents 34 and a central aperture 36 for a purpose soon to appear. At its front end the lid includes a lip 38 adapted to snappingly and releasably engage a protuberance 40 on the container.

Press fit into the bottom of the container is a disk 42 which is limited in its inward movement by a peripheral shoulder 44 in the container wall. Depending centrally from the disk is a protuberance 46, preferably arcuate, for a purpose soon to appear.

At this point it should be observed that the arms, container and lid are preferably fabricated of a non-heat conductive material while the disk is fabricated of a heat conductive material. The non-heat conductive material may be any suitable plastic having a softening temperature above the maximum temperature generated in the container. The heat conductive material may be any suitable metal such as aluminum, brass, etc.

As shown in the drawings, the lower arm.14 is preferably trifurcated and includes a central member 48 joined by two arcuate members 50 and 52, the latter being peripherally contiguous with the margin of the container 28. The trifurcated arm presents a wide bearing surface for a molded tress of hair engaged in the clamp. The portion of the lower arm immediately beneath the disk 42 is normally upwardly inclined from the pivot 20 to the forward end of the container at a predetermined angle, as shown clearly in Figure 5 and for a purpose soon to appear.

Insertable in the container when the lid is open is a packet 54 which is adapted to rest uponthe disk 42. The packet comprises a porous envelope 56, such as paper or cloth mesh, containing a chemical compound or compounds 58. In order that the packet lie flat upon and cover the entire inner surface of the metallic disk 42, it is preferred that a metallic foil 60 be provided to which is crimped and secured the porous envelope 56.

The compound 58 may be potassium or magnesium permanganate. To generate heat in the container for conduction through the metallic disk 42 to the clamped tress of hair, an additional chemical in liquid form can be dropped onto the packet 54 through the perforation 36 of the lid 32 by means of a dropper or a flexible squeeze bottle 60. Said chemical in liquid form may be glycerol which will react exothermally with the permanganate as set forth in the Bonat Patent No. 2,239,410. It will be understood that the contents of the packet and chemical to be added thereto is not limited to those chemicals disclosed in said Bonat patent. Any combination of chemicals may be employed provided they are safe, will not react with the materials from which the present device are fabricated and will react exoth'ermally.

The present invention also comprises a novel method of setting hair dry employing the principles of the above described device. It comprises the clamping of a dry molded tress of hair and applying heat on the molded tress while the latter is subjected to uniform pressure or tension and while the tress is restrained against distortion.

The method is most efiiciently carried out with the above described device as follows. The lid 32 is hinged to the open position and the packet 54 is inserted in the container 28, the latter resting on the metallic disk 42. The lid is then closed and the second chemical in,

liquid form is'dropped-ontc'rthe packetthrohgl'i thecentra l ap ertnre 36 of the lid. W A tress of hair is then molded preferably in the form of a pin curl 62 and clamped, as shown in Figure 3,

Thus the lower'arm will exert uniform pressure or tension on the molded tress in the clamp. In addition, a pin curl always includes a central space or void 64. The protuberance 4 6 of the "disk 42- enters this space; to retain-the pin curl i n its proper molded condition while the latter is'setting. The jheafgenerated in the container, which usually does not 'exceed a temperature of 180 F., is conducted through the metallic dislc to the clamped tress of hair an dee tsthe hair within a matterof five to ten minutes Iyvith'ouf the need for prior wetting of the hair.

I trifiircationof the lower arm 14 permits the arm to 'p'r'es'en't a 'wide bearingsurface on the molded tress.

This together with the factjthatthe lower arm assumes a position substantially parallel to the upper arm and the fact that theprotuberance 46 enters the space 64 of the pin curl permits the curl to be retained in its proper molded condition throughout the entire setting operation. Sinoe'the heat generated in the clamp is suflicient to :set' the molded tress in approximately five to ten minutes, one can begin to remove the first and subsequent clamps V immediatelyafter the last clamp has been applied to the hair. I While a preferred embodiment of the invention has been shown and described hereabove, minor variations thereof may be made without departing from-the spirit a of the invention and the scope of the appended claims. I Thnsfwhile it has been found that Plexiglas V, a thermoplastic acrylic polymer resin, serves efiectively as a 'non-lieat'conductive material from which the device can be fabricated, any other plastic may be employed provided that it has a softening temperature in excess of the maximum temperature generated in the container.
